Subject: [PATCH] x86 Boot enhancements, vmlinux.lds 2/9
Date: 03 Apr 2002 09:02:07 -0700 [thread overview]
Message-ID: <m1adsku5xc.fsf@frodo.biederman.org> (raw)
Linus, please apply.
This patch corrects the vmlinux so it correctly reports the physical
load address of the kernel at 1MB, and the actual kernel entry point.
This is done with a small change to the linker script and removal of
the incorrect command line linker entry point specification.
Eric
